Operating room.

At this moment, in the operating room, the atmosphere is very solemn, and everyone present is tense and nervous, as if facing a great enemy.

Zhao Heng's side has completed the preoperative anesthesia preparations.

But looking at the patient's heart rate and blood pressure, Zhao Heng felt as if he had been on a roller coaster ride together.

"The patient's vital signs are stable and the operation can begin."

Zhao Heng calmed down, looked at the patient's heart rate and blood pressure again, and said to the chief surgeons Liu Ziang and Jiang Rui.

"Okay, let's get started."

Liu Ziang nodded, indicating that the operation had begun.

The first thing to do is cardiopulmonary bypass, to do cardiopulmonary bypass on such a critically ill patient, which is equivalent to dancing on the tip of a knife, and if you are not careful, maybe the patient's heart will not be able to resume beating.

"Dr. Zhao, the artificial heart-lung machine, the variable temperature water tank and the oxygenator are all ready."

Here, Tian Zhen also said to Zhao Heng.

She and Sun Li have already prepared all the equipment for cardiopulmonary bypass.

"Okay."

Zhao Heng nodded.

Next, Zhao Heng and Jiang Rui, the attending doctor of cardiac surgery, completed cardiopulmonary bypass, and Liu Ziang was preparing for a craniotomy.

These tasks are carried out in an orderly manner at the same time, and the entire operating room is like a complex large-scale battlefield, and everyone is responsible for charging into battle at different times.

This is a very common multi-threaded mode of work in the operating room, and as a surgeon, you must be very proficient in this mode of work.

In general, cardiopulmonary bypass orthocardiology surgery uses a median sternal cracker incision, most of which are inserted into the donor vessel through the ascending aorta and a vena cava drainage tube through the right atrium.

The median sternal incision, in layman's terms, is to dissect the patient's chest from the median position, and then directly expose the heart.

This is the same procedure as craniotomy.

Zhao Heng held sternal forceps, Jiang Rui held an electric knife, and with the cooperation of the two, the patient's chest cavity was soon opened.

This opened the chest cavity and saw the heart directly.

Seeing the beating of the human heart up close and directly is a vivid and vivid experience, which is still very shocking.

No matter how many times he watched it, every time he saw this kind of scene, Zhao Heng would always feel a tremor in his heart.

This is a very vivid life, and life and death are in the hands of the chief surgeon, this feeling cannot be experienced without being a surgeon.

Hiss!

As soon as he saw the patient's heart, Zhao Heng gasped.

Because, on the surface of the heart, he saw scars caused by electric shocks, and these scars, which appear radial on the surface of the heart, are very typical of electric shock-like manifestations.

Seeing this scene in front of him, Zhao Heng once again felt that it was a miracle that this patient could survive and go to the operating table.

Next, it depends on whether the miracle will happen again.

"Perform a catheter of the ascending aorta."

Zhao Heng said in a deep voice.

He is an anesthesiologist, and this series of operations on cardiopulmonary bypass is naturally dominated by him.

"Okay."

Jiang Rui nodded.

At this moment, he had already recognized Zhao Heng, but now this recognition has deepened.

Even on the Hopkins side, cardiopulmonary bypass for such a critically ill patient is enough to write a paper and publish it in the main journal SCI.

It's a race against death.

To use a popular analogy, heart surgery is equivalent to a car engine failure, and the engine must be repaired without turning off the engine.

This is heart surgery, cardiopulmonary bypass, such surgery.

Cardiopulmonary bypass, in fact, is to temporarily establish a circulatory system outside the heart to replace the heart, and the heart is temporarily in a state of arrest.

After the surgery on the heart is done, the heart can be back in beating.

The almost unthinkable operation of stopping the heart and resuming it is possible because of the development of modern medical technology.

When the intubation was performed, Zhao Heng's heart was lifted, if the cardiopulmonary bypass was not completed and the patient had cardiac arrest, it would mean that all the subsequent operations did not need to be done.

But fortunately, Zhao Heng has made very full preparations for this patient, so the arterial blood supply - ascending aorta cannulation, venous drainage cannulation - single cannula through the right atrial and superior and inferior vena cava cannulation, left heart drainage cannula, these are all successfully completed.

Looking at the ever-changing numbers on the fluorescent digital continuous display, Zhao Heng breathed a sigh of relief.

The blood flow pressure, flow rate, and oxygen concentration are normal, and the next surgery can be carried out normally.

"Doctor Jiang, it's time to start."

Zhao Heng nodded to Jiang Rui and said.

"Okay."

Jiang Rui, who had been waiting for a long time, took a resident doctor from the Department of Cardiac Surgery to start the repair of the heart valve.

At the same time, Liu Ziang's side was also performing a craniotomy to remove the hematoma in the skull.

Sitting next to a large number of monitors, Zhao Heng was sitting precariously, always paying attention to the real-time data displayed on the monitor.

These data reflect the patient's physical condition at all times.

Minutes and seconds passed.

Three hours later, Liu Ziang took the lead in completing the removal of the intracranial hematoma and closing the skull.

After completing the removal of the intracranial hematoma, Liu Ziang looked at Zhao Heng, who had been in a state of high tension and did not dare to relax for a moment, and was even more appreciative in his heart.

There are not many young doctors like Zhao Heng now.

At this time, Jiang Rui suddenly frowned, as if he had encountered some problem.

"Doctor Jiang?"

Seeing Jiang Rui's brows furrowed, Zhao Heng couldn't help but stand up and ask.

"Doctor Zhao, Director Liu, come and see."

Jiang Rui said to Zhao Heng and Liu Ziang.

As soon as Jiang Rui said this, Zhao Heng and Liu Ziang both walked to the side of the operating table and looked towards the place Jiang Rui pointed to.

Seeing this, Zhao Heng's scalp suddenly became numb, and Liu Ziang was not much better.

Because they see that the surface of the patient's heart is no longer what it looks like, and the heart looks like a rotten peach.

I really don't know how the patient was propped up on the operating table just now?

"This is the sequelae of electric shock, rhabdomyolysis, which must be because the patient himself has a special constitution, and it has not broken out until now."

Jiang Rui explained to Zhao Heng and Liu Ziang.

Rhabdomyolysis is a syndrome caused by the entry of intracellular substances into extracellular fluid, mainly caused by trauma, strenuous exercise, high fever, electric shock, and electrolyte imbalances.

The biggest problem with rhabdomyolysis is that too many broken cell products enter the renal blood vessels, which may lead to serious complications such as acute renal failure and disseminated intravascular coagulation (DIC).

"The heart is just one place, there must be other places."

Zhao Heng said very solemnly.

"Let's complete the surgery first, and strictly prevent the patient from developing acute kidney failure and DIC after surgery."

Liu Ziang thought for a while and made a decision.

"Okay."

Jiang Rui nodded.

Even if the patient survived the operation, he still had to survive acute renal failure and disseminated intravascular coagulation caused by rhabdomyolysis after surgery.
